在我给定的代码中，我用diff-ids动态创建了textbox，在javascript中，我一个接一个地获取textbox的值，直到这里所有的东西都很完美，但当我将这些数据从ajax post方法传递到其他文件时，获取的数据序列将改变
<html>

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.js"></script>
<script>
$(document).ready(function(){
var i = $('input').size() + 1;
$('#add').click(function() {
var value = parseInt(document.getElementById('number').value, 10);
value = isNaN(value) ? 0 : value;
value++;
document.getElementById('number').value = value;
$('<div id="d"><input type="text" id="field'+value+'" name="dynamic[]" value="' + i + '" /><br/><input type="text" class="field1" name="dynamic1[]" value="' + i+i + '" /></div> ').fadeIn('slow').appendTo('.inputs');
i++;
});
$('#remove').click(function() {
if(i > 1) {
$('.field:last').remove();
$('.field1:last').remove();
i--;
}
});
$('#reset').click(function() {
while(i > 2) {
$('.field:last').remove();
$('.field1:last').remove();
i--;

$('.submit').click(function(){
var number = document.getElementById("number").value;
for(var i=1;i<=number;i++)
{
answers = $('#field'+i).val();
alert(answers);
$.ajax({

data: {answers:answers},

success: function(html)

alert(html);

return false;

上面的代码不起作用。您在第一个输入字段中错过了类，您保留了id而不是类名。
$(document).ready(function(){
var i = $('input').size() + 1;
$('#add').click(function()
{
$('<div class="d"><input type="text" class="field" name="dynamic[]" value="' + i + '" /><br/><input type="text" class="field1" name="dynamic1[]" value="' + i+i + '" /></div> ').fadeIn('slow').appendTo('.inputs');
i++;
});
$('#remove').click(function() {
if(i > 1) {
$('.field:last').remove();
$('.field1:last').remove();
i--;
}
});
$('#reset').click(function() {
while(i > 2) {
$('.field:last').remove();
$('.field1:last').remove();
i--;
}
});
});
</script>
<style>
.field{
padding:0 0 0 0;
margin: 0 5px 24px 78px;
}
.field1{
padding:0 0 0 0;
margin: 0 5px 24px 78px;

<form method="post" action="dd.php">

<input name="submit" type="submit" class="submit" value="Submit">
